Hello, Thank you for your help, I really appreciate it, I was able to solve the problem! Here is a part of my dataframe (just in case...):
dput( head( behavioral_df) )
structure(list(ID = c(1, 2, 3, 4, 5, 6), DOB = c("9/53/1959",
"4/8/1953", "2/21/1961", "10/11/1948", "9/4/1962", "8/22/1953"
), startpoint = c(2.33, 2.44, 1.57, 3.1, 2.78, 1.89), endpoint = c(3.5,
4, 2.4, 4.02, 3.98, 2.1), `1_t1_start` = c(1, 1, 1, 1, 1, 1),
`1_T1` = c(4, 7, 2, 3, 3, 5), `2_T2_start` = c(2.67, 3.3,
2.45, 2.2, 1.9, 2.6), `2_T2` = c(5, 5, 6, 4, 5, 3), `3_T3_start` =
c(4.76,
5.1, 3.87, 3.61, 2.83, 3.7), `3_T3` = c(7, 3, 4, 2, 5, 3),
`4_T4_start` = c(6.09, 6.99, 5.21, 5.19, 5.02, 6.34), `4_T4` = c(4,
5, 5, 4, 3, 6)), row.names = c(NA, -6L), class = c("tbl_df",
"tbl", "data.frame"))

Hi Anne,
As mentioned above, you may have to do nothing. Here is an example
that might clarify that:
azdat<-read.table(text="subject 1 2 3
1 10 20 30
2 11 22 33",
header=TRUE,stringsAsFactors=FALSE)
azdat
subject X1 X2 X3
1 1 10 20 30
2 2 11 22 33
As you can see, R simply prepends an "X" to numeric names. If you
really want a "v":
names(azdat)<-gsub("X","v",names(azdat))

Dear R users, I have a dataframe that contains several variables, among which 105 correspond to scores on certain trials. Unfortunately, when I imported
this
dataframe into R, I realised that the variable names corresponding to
each
trial begin with digits, which violates R naming conventions. I am trying to relabel these variables by adding a 'v' as a prefix to
each
of them, I'd like to use tidyverse, but I am struggling with this process of renaming. When I run this chunk of code, no error occurs but my variables are not renamed. I'm fairly new to R and I can't understand
what
I'm doing wrong.
```{r}
behavioral_df <- behavioral_df %>% rename_with(.fn = ~paste0("v"),
starts_with('^\\d'))
```
I appreciate if you can help.
Best,
Anne
